The best HVAC deals never reach a banker's list.
Proprietary deal flow from owners who came for a valuation rather than an auction. Anonymous listings, verified sellers, and direct access to the decision maker.
No cost to review. Transaction fee paid at close.
Institutional capital has already voted.
The trades went from an overlooked corner of the lower middle market to a core home services thesis in under a decade. Recent transactions:
Why HVAC became a core thesis
The characteristics that drew capital into HVAC are unusually well suited to a buy-and-build strategy, and they are structural rather than a function of any particular vintage.
- Non-discretionary demand. A failed system in July is not a deferrable purchase. Revenue holds through consumer weakness in a way that most home improvement categories do not.
- Recurring revenue exists natively. Maintenance agreements are an established industry practice, so the annuity component does not have to be invented, only expanded.
- Clean working capital. Residential work is largely cash or financed at the point of sale, so receivables are short and bad debt is minimal compared with commercial contracting.
- Structurally defensible. The work cannot be offshored, is resistant to automation, and requires licensure and physical presence in the market.
- Extreme fragmentation with a demographic catalyst. The industry remains overwhelmingly owner-operated, and a large cohort of founders is reaching retirement without a succession plan. Supply of sellers is not the constraint.
- Real operational upside. Most independents run without disciplined pricing, structured sales processes, dispatch optimization, or membership programs. Margin expansion post-close is achievable rather than theoretical.
The multiple arithmetic
The strategy works because of a persistent and well-understood spread. Small owner-operated companies transact in a band around 5x to 7x EBITDA. Mid-sized businesses with management depth trade around 6x to 9x. Scaled regional platforms with diversified geography, real systems, and institutional reporting have transacted at multiples several turns higher.
An acquirer that buys add-ons in the low-to-mid single digits and integrates them into a platform valued on a materially higher multiple creates value through the arithmetic alone, before any operational improvement. Add the margin expansion available from pricing discipline, membership growth, and route density, and the return profile becomes clear.
The binding constraint is not capital and it is not the thesis. It is sourcing. Every platform is chasing the same intermediated processes, which is exactly where competition compresses entry multiples and erodes the spread the strategy depends on.
Where proprietary flow actually comes from
An owner who has hired a banker has already decided to sell, already assembled a book, and is already talking to your competitors. By the time that opportunity reaches you, the pricing reflects a competitive process.
Owners arrive here at a different point. They come for a free, anonymous valuation, often a year or more before they intend to transact, because they want to know what their company is worth. Some of them decide to list. That produces a pipeline of sellers who have not engaged an intermediary and whose businesses have not been circulated.
It is worth being direct about the tradeoff. Earlier-stage sellers are frequently less prepared than a banked process would deliver. Financial packages vary in quality, some owners are still deciding, and you may need to invest more time educating a counterparty. In exchange you get first look, a direct relationship with the decision maker, and pricing that has not been set by an auction.
Platform and add-on economics
| Target profile | Typical entry multiple | Role in the strategy |
|---|---|---|
| Under $500K EBITDA | 5.0x – 7.0x | Technician and customer-base tuck-in; high owner dependency |
| $500K – $3M EBITDA | 6.0x – 9.0x | Core add-on; the majority of transaction volume |
| Above $3M EBITDA | 6.5x – 10.0x | Platform anchor or regional hub; scarce, moves quickly |
| Multi-trade operator | 5.5x – 8.5x | Cross-sell density in a single market |
| Over 50% recurring revenue | +1.0x | Applied on top of the ranges above |
What we ask of buyers
Verification covers the firm, available capital, and acquisition mandate. This is not a formality. Sellers on this platform are trusting that their anonymity holds and that their information reaches parties who can genuinely transact, and that trust is the entire reason the inventory exists. Buyers who treat listings as market research rather than acquisition intent lose access.
Access is open to private equity platforms and their add-on programs, family offices, independent sponsors with committed or credibly sourced capital, search funds, and strategic acquirers already operating in the trades.
What separates a good HVAC target from a cheap one.
The four areas that most reliably explain post-close disappointment.
Active agreement count, renewal rate, and revenue under contract, verified against the field service system rather than taken from a summary schedule.
Who quotes, who dispatches, who owns the key relationships. If the answer is the seller in every case, the earnings may not survive the transition.
Crew tenure and turnover history. Labor is the constraint on integration, and a company that cannot hold technicians cannot absorb growth.
Storm years, freeze events, pandemic-era distortions, and owner add-backs. The stated EBITDA and the underwritable EBITDA are frequently different numbers.
Common questions from acquirers.
Why has private equity concentrated on HVAC?
HVAC combines non-discretionary demand, recurring maintenance revenue, cash-pay customers with minimal receivable risk, resistance to offshoring and automation, and a highly fragmented ownership base with an aging seller population. That combination supports a buy-and-build strategy where a platform can be assembled from smaller companies and exit at a materially higher multiple.
What is the difference between a platform and an add-on acquisition?
A platform is the anchor investment, typically a larger business with management depth and systems capable of absorbing other companies, and it commands the highest multiple. Add-ons are smaller companies acquired at lower multiples and integrated into the platform. The spread between the add-on entry multiple and the platform's blended exit multiple is a primary source of return in this strategy.
What EBITDA range do most HVAC add-ons fall into?
The majority of add-on transactions involve companies between roughly $500K and $3M of EBITDA, generally trading in a 6x to 9x band. Companies below $500K price lower and carry more owner-dependency risk. Platform candidates above $3M price above the band and are considerably scarcer.
How does SellSideTrades source proprietary deal flow?
Owners come to the platform for a free anonymous valuation, often well before they are ready to transact, and some of them choose to list. That produces a pipeline of sellers who have not engaged an intermediary and whose businesses have not been circulated through a broad auction process.
Can independent sponsors and family offices get access?
Yes. Access is open to private equity platforms, family offices, independent sponsors with committed or credibly sourced capital, search funds, and strategic acquirers already operating in the trades. Verification covers the firm, available capital, and acquisition mandate.
Source deals before they are shopped.
Verification takes minutes. Reviewing listings costs nothing.
